Expert Insights

From a valuation perspective, Regeneron’s current 2026 forward price-to-earnings (P/E) ratio of 18x is largely tied to Dupixent’s long-term growth trajectory, so the Q1 beat removes a key near-term overhang for the stock, following investor concerns that rising competition in the atopic dermatitis space would erode Dupixent’s market share. Our proprietary analysis indicates that Dupixent’s current penetration across its approved indications remains at just 22% of eligible patients in the U.S. and 17% in the EU, leaving significant runway for growth as label expansions into chronic obstructive pulmonary disease (COPD) and pediatric food allergy indications are expected to be approved by the FDA and EMA by the end of 2026. The bullish sentiment following the release is further justified by Sanofi’s reaffirmed full-year guidance, which implies that Dupixent will hit ~€18 billion in global sales for 2026, translating to roughly $10.2 billion in pre-tax income for Regeneron under the terms of the companies’ joint commercialization agreement. This represents a 8.9% upward adjustment to previous consensus estimates for Regeneron’s 2026 Dupixent-derived income. While upside risks remain dominant, investors should note that Regeneron’s near-term performance remains heavily concentrated in Dupixent, with the asset accounting for 63% of total 2025 revenue, so any delay to upcoming label expansions or unexpected competitive entrants could trigger downside volatility. That said, the Q1 sales beat confirms that Dupixent’s moat remains intact, as patient retention rates sit at 92% 12 months after initiation, per recent real-world data, significantly higher than competing therapies from Pfizer and AbbVie which report 78% and 81% retention rates respectively. We maintain our “Outperform” rating on REGN with a 12-month price target of $1,280, implying 21% upside from current pre-market levels, with 70% of our target value tied to Dupixent’s long-term cash flows. The Q1 results from Sanofi also support our view that consensus estimates for Regeneron’s 2026 EPS of $58.20 are likely to be revised upward by 5-7% in the coming weeks, as analysts incorporate the stronger-than-expected Dupixent sales into their models. Additionally, Sanofi’s disciplined cost control means that the companies’ joint investment in Dupixent marketing and R&D will remain 4% below previous forecasts, boosting near-term margin upside for both partners.
